Title: Indicating device for fault of power supply
Inventor: NAKANO MASAO
IPC: H04R3/00
Filed: 1981-08-21
Abstract: PURPOSE:To give a warning signal through a speaker although power supply voltage is much less than a prescribed level for an indicating device for audible power supply fault, by giving an audible indication directly to a speaker regardless of an active mode of an amplifier. CONSTITUTION:An audio amplifier 30 can receive an audio signal input 32 and at the same time receives a stopping signal for the operation of the amplifier via an input 38. With application of the stopping signal, the bias of a transistor of a power amplifying stage is cut for the amplifier 30. Otherwise the operation of the amplifier 30 itself is stopped. The positive supply voltage +B is applied to the amplifier 30 through a terminal 40, and the amplifier 30 is grounded via a connecting line 41. As a result, a warning signal for power supply fault can be produced from a speaker 34 by applying the signal of an audible frequency through an input terminal 48 although the amplifier 30 becomes inactive with the input 38.

Title: One side oxidation of metal belt and apparatus therefor
Inventor: YOKOYAMA HIDEO
IPC: C23C8/02
Filed: 1977-11-01
Abstract: PURPOSE:To assuredly achieve one side oxidation, an oxidizing gas is jetted on an activated surface of metal belt, when a deflector roll contacts the metal and changes its moving direction. CONSTITUTION:A steel belt to be galvanized is cleaned, activated in a reducing furnace and then it is curved while changing its moving direction by contacting a deflector roll 1. On the curved surface, an oxidizing gas such as air is jetted through nozzles 2 and non-oxidizing gas such as nitrogen is jetted through nozzles 4. Suction holes 3 between nozzles 2 and 4 suck in a sufficient amount of these gases to prevent diffusion of oxygen and nitrogen. The treated steel belt is then introduced into a galvanizing bath for one side galvanization. The process assures effective one side oxidation of steel belt without deteriously affecting the other side to be galvanized.

Abstract: PURPOSE:To send a pulse signal of a double frequency by frequency-dividing an input signal into 1/2 and applying exclusive OR processing to a non-delay signal and a 90 deg. delay signal from the divided signals viat two photocouplers respectively so as to recover the input signal. CONSTITUTION:In receiving a picture signal e1 desired to be sent, a 1/2 frequency division circuit 11 divides the signal e1 into 1/2 to output a frequency division signal e11, which is inputted to the photocoupler 12. The signal e11 inputted to a 90 deg. phase delay circuit 13 is inputted to a photocoupler 14 as a 90 deg. phase lag signal e12. The signals e11,e12 are sent to the output side by the photoelectric coupling offering electric isolation to an input and output of the photocouplers 12 and 14. Output signals e01,e02 from the photocouplers 12, 14 are given to an exclusive logic circuit 15. Since the phase of the output signal e01 is shifted by 90 deg. from the phase of the signal e02, the exclusive OR circuit 15 outputs an output signal e0 having the same frequency as the input signal e1.

CONSTITUTION:Even when the operation of a compressor is stopped, a cooler 13 is cooled by the cold heat dissipation of a cold heat accumulator 19 and the cold air is delivered into a cold storage chamber 41 in accordance with the opening degree of a damper 65 whereby the cold storage chamber 41 is cooled. The temperature of the cold heat accumulator 19 upon finishing the accumulation of cold heat is #-29 deg.C while the temperature of the cold heat accumulator is risen by heat leak after finishing the cold heat accumulation and the blow-off cold air temperature of the cooler 13 becomes -15--10 deg.C during cold heat accumulating cooling operation. The temperature sensitive section 103 for regulating the opening degree of the damper is arranged near a cold air suction port 67 and, therefore, the temperature of the temperature sensitive section 103 may be reduced to +0.1 deg.C whereat the opening degree of the damper becomes zero. Accordingly, the problem of freezing in the cold storage chamber 41 will never be generated.

Filed: 1987-05-29
Abstract: PURPOSE:To facilitate the reproduction signal processing by selecting a pit signal width in the case of high density recording to a degree not causing waveform interference as a minimum signal width in the mark end recording system. CONSTITUTION:Minutes pits are arranged so as to make the pit interval of the minute pits narrow to a degree not subject to waveform interference due to adjacent minute pits for a reproducing signal read from the minute pit array, and an intermediate level between a maximum level and a minimum level is obtained from the reproducing signal read from the array of the minute pits. Moreover, a beam radiation time T to form the minute pits is obtained in advance so that a half width time T2 of a pit signal corresponding to the minute pits clipped by two points crossed with the intermediate level and a half width time T1 of the signal at a pit interval part corresponding to the pit interval clipped by two point crossing with the intermediate level are made equal to each other. Then the radiation time of pit forming beam is controlled to generate pits,.
